I'm running 4.3.34 on a FreeBSD 10.2-STABLE #1 r292065 host. My 3 guests 
are all FreeBSD with the exact same kernel.

I keep getting this:

422:48:23.470075 PIIX3 ATA: Ctl#0: RESET, DevSel=0 AIOIf=0 CmdIf0=0xca 
(30020391 usec ago) CmdIf1=0xa0 (-1 usec ago)
425:26:57.329048 PIIX3 ATA: execution time for ATA command 0xca was 9543 
seconds
425:26:57.422452 PIIX3 ATA: Ctl#0: finished processing RESET

398:44:12.032405 PIIX3 ATA: Ctl#0: RESET, DevSel=0 AIOIf=0 CmdIf0=0xca 
(30033917 usec ago) CmdIf1=0xa0 (-1 usec ago)
398:44:12.079466 PIIX3 ATA: execution time for ATA command 0xca was 30 
seconds
398:44:12.079489 PIIX3 ATA: Ctl#0: finished processing RESET

The net result of this reset is the guest OSes report "out of inodes" 
even though a df -i clearly shows tons of them.

I'm not sure where else to continue to debug this. I've ensured that all 
kernels are exactly the same, and all virtualbox software is from the 
same version. Would anyone care to help shed light on this problem?
Should I file a bug report? Thanks in advance.

Due to confusion, people mistake things for themselves;
covetousness flares up, and they get into vicious cycles
that cloud perceptions and enshroud them in ignorance. The
vicious cycles go on and on, and people cannot be free.
